Shinsekai yori, Selector Infected WIXOSS Recommendations
Both are heavy psychological shows with slow pacing and lots of foreshadowing built upon the dark secrets of a seemingly innocent body. Each has very mature themes that are handled extremely well, but may be lost on those who aren't paying enough close attention. Shinsekai Yori spends most of its time on some incredible world building whereas WIXOSS opts to spend more time on its characters, but these anime are fundamentally written the same way with the same goals in mind. If you liked one, you will probably like the other.
